The PS4 is built with a custom Ryzen-based APU. Because Ryzen is x86_64-based, it's likely possible that they could also make machines that are architecturally compatible- they could probably get away with a compute box filled with similar, if not better, graphics chips / cards, use an EPYC processor with all its cores and PCIE lanes to connect everything up, and then virtualize it.
For the PS3, however, they would definitely need something very custom- their Cell processors are very different from anything else on the market, but they also already have a service for that, but I have no idea how those work- they obviously have something, though.
